    Hi,

    Thanks in advance of any help you guys can offer. I have searched the
    groups for similiar problems and come up dry, so heres my question:

    We run small WISP in midlands UK, using Cicso AP1200s as Access Points, and
    typically Smartbridge airBridge clients (indoor and outdoor models).
    Recently our supplier sent us some airPoint indoor units instead of the
    typical airBRIDGE indoor units. No worries, we thought since they run in
    operational mode 'client bridge' should work OK right? wrong.

    client will associate with AP, but AP only shows 0.0.0.0 as IP address for
    client. good signal (-61db) on both ends, but laptop cannot ping, no data
    moves, no IP address gets registered with AP.

    Here is my theory and I am certain I am wrong or my understanding is flawed,
    so if you can enlighten me, please do:

    802.11b spec provides for 4 address fields. Address field 1 - 3 is
    usually used in the following ways:
    AD-HOC destination stations, source station, and BSSID. (address 4 not
    used)
    INFRASTRUCTURE MODE: source station, destination station, and either the
    sending or receiving AP (address 4 not used)
    WDS MODE: Sending and receiveing AP, Destination Station, but also uses
    Address 4 for source station.

    Address 4 only comes into play when in WDS mode (two APs communicating, with
    one usually in bridge mode, but not necessarily)

    finally the climax... Does anyone know if the Cisco aironet 1200 AP
    (AIR-AP1230B-E-K9 w IOS C1200-K9W7-M) have another use for address 4? or
    does the smartbridge airPoints SB2400 have a problem with the use of address
    4? or ... is there a setting in the AP1200 that allows the use of address 4
    for conectivity by other makes/models of AP in client bridge mode?

    sorry to bother if its a simple one, but we're still quite new to Cisco kit,
    and smartbridge isn't very forthcoming with their architecture

    cheers for the help

  2. Sorry I can't help with the Cisco part, but I have several airPoints in
    use as client bridges connecting to other airPoints in AP mode with no
    issues at all. You might try asking on the isp-wireless list:
    mailto:

    For contacting smartBridges, by far the fastest way to get a response is
    the mail list at:
